SPECIFICATION forming part of Letters Patent No. 695,906, dated March25, 1902.

Application filed September 28, 1901. Serial No. 76,827. (No model.)

To ctZZ whont it may concern:

Be it known that I, JUDSON BUCHANAN, a citizen of the United States,residing at Chattanooga, in the county of Hamilton and State ofTennessee, have invented certain new and useful Improvements inWheel-Flows; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to whichit appertains to make and use the same,reference being had to the accompanying drawings, and to letters ofreference marked thereon, which form a part of this specification.

My invention relates particularly to wheelplows having a pair of wheelsforward of the moldboard and a caster wheel or trailing wheel locatedrearwardly of the moldboard.

The object of my invention is to provide a more complete adjustment ofthe frame or beam to which the moldboard is attached, whereby the propervariations in inclination and elevation of the moldboard may be securedto compensate for wear of the moldboard. To secure suchadjustment,provision must be made for independently raising or loweringthe beam or frame with reference to each of the three wheels of theplow.

The moldboard may be of the ordinary fixed form or of the rotary or diskform. T0 attain the best results, both of said forms require adjustmentin all of three directions first,in a vertical direction; second, forproper inclination with reference to a plane which is vertical andparallel to the length of the machine; third, for proper inclinationwith reference to the front and rear of the machine. If the adjustmentis to be made in a vertical direction without changing the inclination,the frame or beam should be raised or lowered equally with reference toeach of the three wheels. If the moldboard is to be made to inclinetoward the right, the left-hand wheel is raised or the right-hand wheelis lowered. If the moldboard is to be inclined toward the left, theright-hand wheel is raised or the lefthand wheel is lowered. If themoldboard is to be inclined backward, both front wheels are raised orthe rear wheel low ered. If the moldboard is to be inclined forward, therear wheel is raised or both the front wheels lowered. Obviously thisinclination may be accomplished by the proper partial elevation anddepression of the three wheels.

This general statement is made in order that my improvement, whichrelates only to the adjustment of the rear or caster wheel, may be morereadily understood.

In the accompanying drawings, Figure 1 is a side perspective view of theplow embodyin g myimprovement. Fig. 2 is a vertical section on line 2 2of Fig. 3lookingin the direction of the arrow." Fig. 3 is a plan of theportion of the plow involved in making the coupling between thecaster-wheel and the plowbeam. Fig. 4 is a side elevation of thebearing-block into which the'caster-arm is journaled.

A is the moldboard.

B is the right-hand front wheel.

0 is the left-hand front wheel.

D is the tongue or front beam.

E is the front axle.

F is the beam.

G is the caster-wheel or rear wheel.

H and I are rack-levers for adjusting the elevation of the front of themachine at either side.

As my improvement does not extend to the means for adjustment at thefront of the ma chine, I deem it unnecessary to' describe in detail themechanism used for this purpose.

J is the caster-wheel arm, which has at one end a lateral axle J,extending through the hub of the wheel G, and at the other end thevertical journal J extending through the caster-bearing block K. Saidbearing-block has a tubular bearing K of proper depth and internaldiameter to receive said journal J At its lower end said journal J 2extends through said bearing and receives the transverse cotter-pinf.Said bearing-block is so applied to the beam F as to permit relativevertical adjustment between said members. Either of said members may bemade with a broader vertical face than is needed for binding saidmembers together in only one position. The drawings show saidbearing-block made approximately twice as wide in a vertical directionas the lateral face of the beam F, and said block is provided withvertical transverse slots K and the beam is provided with correspondingcircular holes F for the reception of bolts L, extending through saidbeam and block. By tightening said bolts said block and beam areimmovably bound together. Heretofore said block has been made onlyapproximately as wide in the vertical direction as said beam andprovided with round apertures corresponding to similar apertures throughthe beam. This construction permitted the binding of said block and saidbeam together in only one position. With such construction the rearwheel could not be adjusted for varying the rearward'and forwardinclination of the moldboard. The side of the beam F to which said blockK is applied is preferably provided with longitudinal ribs F while thebearing-block is provided on the opposing face with corresponding ribs Kthe ribs I? being adapted to rest in the spaces between the ribs K Aheavy washer L may be interposed between the beam and the end of thebolt L. The drawings show such bearing-block provided with a sufficientnumber of ribs to permit the application of said block and the beam F toeach other in four different positions. They are shown applied to eachother, with said block in the lowerposition. This places the rear end ofthe beam at the highest elevation and inclines the moldboard forward asfar as this may be accomplished by the adjustment of the rear wheel. Thesaid bearingblock has mounted upon its rear an oblique shoulder Kagainst which the arm J rests when the caster-wheel Gstands in itsrearmost position. Said wheel is free to swing upon the journal J towardthe left. The seatstandard M is shown applied to the front of saidbearing-block upon an oblique vertical face M. Said bearing-block is asingle-piece casting.

I claim as my invention 1. In a Wheel-plow, the combination of acaster-wheel, a caster-wheel'arm having a vertical journal, bolts, twomembers, one a beam supporting the moldboard and the other abearing-block for said journal and having a shoulder, K, the meetingfaces of said members being vertical and provided with interlockingribs, and one of said members being adapted to receive said bolts whilesaid member is at any one of a plurality of elevations compared with theother of said members, substantially as described.

2. In a wheel-plow, the combination of a caster-wheel, a caster-wheelarm having a vertical journal, two members, one a beam supporting themoldboard and the other a bearing-block for said journal and having ashoulder, K one of said members having vertical slots to receive bolts,substantially as described.

3. In a wheel-plow, the combination of a caster-wheel, a caster-wheelarm having a vertical journal, bolts, two members, one a beam supportingthe moldboard and the other a bearing-block for said journal, themeeting faces of said members being vertical and parallel to the lengthof said beam and provided with interlocking ribs, and one of saidmembers being adapted to receive said bolts while said member is at anyone of a plurality of elevations compared with the other of saidmembers, substantially as described.

4. In a wheel-plow, the combination of a caster-wheel, a caster-wheelarm having a vertical journal, bolts, two members, one a beam supportingthe moldboard and the other a bearing-block for said journal and havinga shoulder, K the meeting faces of said members being vertical andparallel to the length of said beam and provided with interlocking ribs,and one of said members being adapted to receive said bolts while saidmember is at anyone of a plurality of elevations compared with the otherof said members, substantially as described.

In testimony whereof I affix my signature, in presence of two witnesses,this 26th day of September, in the year 1901.
